IPC: B41J2/055
Filed: 1983-03-08
Abstract: PURPOSE:To make it possible to dissolve a problem caused by the shift of a bonding position, by providing a groove, which has a width being 5-30% on the basis of that of a pressure chamber, to the thin plate of an electromechanical converter so as to surround a position where a piezoelectric element must be bonded while bonding said element to the position surrounded by said groove.

Title: Manufacture of nonaqueous solvent cell
Inventor: NISHIYAMA TOMOHIRO
IPC: H01M6/50
Filed: 1986-02-25
Abstract: PURPOSE:To reduce the voltage delay phenomenon by storing a cell at a specified temperature for a specified term after assembling the cell. CONSTITUTION:After assembling a cell it is stored at a high temperature of 90-110 deg.C for 120-480hr, so the growth of an inactive film on the surface of the negative electrode is suppressed. When the ambient temperature is kept at a value lower than 90 deg.C the growth of the inactive film is accelerated faster than at normal temperature, and the voltage delay phenomenon is increased. And at a temperature higher than 110 deg.C the self-deterioration of the cell arises undesirably. And when the storage term is shorter than 120hr the delay of the voltage is not so different as conventional, and when it is longer than 480hr the capacity is decreased undesirably.

Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To dispense with a discrete tie-layer for ensuring adhesion of a coating material to a substrate by forming an adhesion promoting layer on the substrate and a releasing layer thereon and further incorporating an anticorrosive material and a binder in the adhesion promoting layer. SOLUTION: The adhesion promoting composition is applied to the substrate and cured within 48 hours to form the adhesion promoting layer. The fouling material releasing composition is applied onto the adhesion promoting layer and cured for at least 18 hours to form the releasing layer. The anticorrosive material can be applied to the substrate to form an anticorrosive layer prior to the formation of the adhesion promoting layer. The anticorrosive layer contains the anticorrosive material comprising an optional material capable of hindering corrosion or deterioration of the substrate by reaction of the substrate with a material in the surrounding environment. The adequate binder contains a moisture-curable grafted copolymer and further a polydialkysiloxane and one or more ethylenic unsaturated monomers.  Therefore, the application of the discrete tie-layer is not necessary for ensuring the adhesion of the fouling material releasing coating material to the substrate.

Title: Orientation treating agent for liquid crystal cell
Inventor: KOMASA NOBUAKI
IPC: G02F1/133
Filed: 1988-02-23
Abstract: PURPOSE:To more efficiently drive a liquid crystal cell by using a polyimide resin which has a prescribed repeating unit and is higher in dielectric constant than heretofore as an orientation treating agent for a liquid crystal cell. CONSTITUTION:R<1>, R<2> in the repeating unit expressed by the formula are respectively the same or different divalent org. groups, R<3> is a tetravalent org. group constituting tetracarboxylic acid or the deriv. thereof. The polyimide resin having such repeating unit is obtd. from the diacid anhydride of tetracarboxylic acid and diamine such as p-phenylene diamine as starting raw materials. Such polyimide resin or polyamic acid intermediate soln. is coated on a transparent substrate with transparent electrodes and is cured at 150-250 deg.C and is subjected to a rubbing treatment, by which the orientation treating agent for the liquid crystal cell is obtd. Since this resin has a -CONH- group in the molecular skeleton, the dielectric constant and film polarity are higher than the electric constant and film polarity of the conventional polyimide resin and the voltage to be applied on the liquid crystal layer increases. The liquid crystal molecules are thus uniformly oriented and the efficient driving of the liquid crystal cell is enabled.

Title: Method of treating sewage
Inventor: ARIMITSU HIDENOBU
IPC: C02F9/00
Filed: 1978-04-04
Abstract: PURPOSE: To rapidly, safely and efficiently treat sewage from municipal and residence mainly as living waste water and to produce condensed dehydrated sludge.  
     CONSTITUTION: After lime and acrylic amide anion high polymer coagulant are added to sewage for agglomeration and sedimentation, it is biologically treated. The lime is added at least 50mg/l (by CaCO 3  conversion) not to exceed 200% of non-calcium bicarbonate alkalinity of the sewage. The coagulant is set to 0.2 to 0.5mg/l. Thus, the suspended material and BOD removal rate is largely increased in the step of agglomerating and sedimenting the sewage. It can retain an optimum pH at biological step without neutralization for efficient biological treatment and for easy sludge treatment due to less excessive sludge production.
